Unlike its sister ship the EC225, the EC175’s main gearbox has no backup lubrication system, which could present a problem should it experience a total loss of oil. To compensate for this, its components have been designed to withstand the absence of lubricant for a limited period of time. Airbus Helicopters so far has certified a 15-minute dry-run capability (which involved a 30-minute demonstration). Further tests are scheduled for 2015 in a bid to increase the certified duration to at least 30 minutes.

Airbus Helicopters’ planned production rate is now more than 30 EC175s a year.

Certification in hand, Airbus Helicopters is endeavoring to ensure a faultless entry into service of its EC175 medium twin, a critical product for the company in the highly competitive offshore oil-and-gas market. The first delivery, to Belgium-based operator NHV, is planned for the second half of this year, almost five years after the first flight. Thanks to the unprecedented preparation at the company’s headquarters in Marignane, France, and at a customer base, program officials believe an EC175 will be able to operate immediately after delivery.

The Project Zero all-electric vertical-lift aircraft.

AgustaWestland last month received the 2014 American Helicopter Museum and Education Center’s achievement award for “advancements in rotary-wing technologies,” based on the Project Zero tiltrotor demonstrator program. Dr. James Wang, the manufacturer’s research-and-development vice president, accepted the award. Led by Wang, the Project Zero team designed, built and flew a 2,200-pound, all-electric vertical lift aircraft in six months. A few flights took place in 2011-2012.

Russian Helicopters is stepping up efforts to strengthen its base of international partners. The move is in part driven by the fact that it can no longer count on Ukrainian engine suppliers Motor-Sich and Ivchenko-Progress in the wake of ongoing political tensions.

Airbus Helicopters recently exhibited some new EMS equipment for the just-certified EC145T2 light twin. Developed with Mecaer, the new cabin installation is available with an “EMS fixed provisions” option. This provides standardized interfaces for customized hardware, thus reducing the outfitting lead time of an interior for medical operations.

The long quest by the U.S. Air Force to acquire a new combat rescue helicopter (CRH) appears to have concluded, with Sikorsky’s announcement that it has received an engineering and development (EMD) contract worth an estimated $1.28 billion for a derivative of the UH-60M Black Hawk.

A Sino-Russian effort to develop a new advanced heavy helicopter was discussed during the recent visit to Shanghai by a Russian delegation headed by President Putin. According to Russian Helicopters general director Alexander Mikeyev, his company has been discussing the project with China’s Avicopter since 2008. “The main parameters of the project have been agreed on. But the work is not yet complete,” he said.

The emergency lubrication system of the EC225 was modified last summer. EASA approved the changes, including replacing the air and glycol pressure switches, modifying the glycol pump and improving the system’s maintenance. The modification eliminates false alarms and cancels flight manual limitations. In other words, a crew can count on a 30-minute lubrication backup in the event of total loss of oil.

The modification approval went relatively unnoticed last year, as the focus last summer was on the shaft itself.

VIP version of Airbus Helicopters’ EC175.

Airbus Helicopters (formerly Eurocopter) is here exhibiting the Hermès luxury version of its EC135, and is soliciting new possibilities for customization. The helicopter manufacturer (Booth 6613) is seeing a steady market in private and business aviation, with a combined 150 helicopters sold in the world last year by rotorcraft OEMs. Company design engineers are now working on the VIP version of the EC175, with hinged doors and an escalator for passengers.

MD 540A in Jordan

MD Helicopters showed off its prototype MD540A armed scout helicopter last week at the Sofex show in Jordan, marking the type’s first appearance outside the U.S. The choice of venue was made to highlight the type’s credentials in an area where its hot-and-high performance is of considerable interest, at a show where its special-forces support capability is highly relevant, and in a country that has a requirement for a new armed helicopter.
